1. 20 Claims. This invention relates to separable fastener stringers.More particularly, the invention deals with a removable top stopcomprising a yoke like member adapted'for attachment to a predeterminednumber of end scoops at one end of a stringer in forming substantiallywithin the boundaries of the scoops a means blocking end scoops fromcoupling engagement, thus checking.

movement of a conventional slider in the direction of said end of thestringers. Still more particularly, the invention includes a top stop.device having means thereon preventing displacement of a slider from asingle stringer as and when the stringers are completely separated. Thenovel features of the invention will be best understood from thefollowing description when taken together with the accompanying drawing,in which certain embodiments of the invention are disclosed, and inwhich the separate parts are designated by suitable reference charactersin each of the views, and in which:

Fig. 1 is a side view of one end portion of the 2 stringers. On theother hand, the degree of this movement can be determined by thelocation or arrangement of the top stop on the scoops or by the numberof scoops engaged thereby.

In illustrating one adaptation and use of the invention, I have shown inFigs. 1 and 2 at N a part of a stringer tape upon the beaded edgestringer of a separable fastener illustrating a top stop mounted on endscoops of the stringer.

Fig. 2 is a front edge view of the structure as seen in Fig. 1.

Fig. 3 is a section on the line 33 of Fig. 1, diagrammaticallyillustrating the manner of attaching the yoke to end scoops in formingthe top stop.

Fig. 4 is a perspective view of a top stop yoke, detached.

Fig. 5 is a view similar to Fig. 4, showing a modified form of device;and

Fig. 6 is a view similar to Figs. 4 and 5, show-' ing anothermodification.

In separable fasteners of the class defined, there are times when it isdesirable to remove top stops from the stringers. In most instances,these tops have been directly applied to the stringer tapes, and removalof the stops results in damage to the tape.

It is the purpose of my invention to provide a top stop which isdirectly applied to the coupling end portions of two or more scoops andis in the form of a simple yoke shaped body which can be easily appliedto the scoops and also easily removed therefrom. Attachment anddetachment of the stop to the scoops in no way will mar or injure thetape. Furthermore, I provide a top stop device which is substantiallycontained within the boundaries of side surfaces .of the scoops so thatthe stop can enter the channels of the conventional slider and therebypermit movement of the slider to the extreme end of the ll of which issecured, at longitudinally spaced intervals, a plurality of scoops l2.The scoops are generally of the coreless V-shaped cross sectional form,illustrated in the. application of Louis H. Morin on Scoops forseparable fastener stringers Ser. No. 531,618 filed April 18, 1944,being modified solely by employing wing like male coupling end portions,l3 which converge in the direction of the ends it and [5 thereof insteadof having substantially parallel walls, as illustrated in theapplication in question. The re-" cessed or female coupling portions [6of the scoops are recessed at their sides, as seen at I] and l8,v noteFig. 3. The ends I and 15 are, however, substantially inalinement withthe sidesurfaces l9 and 20 of the mounting end portion 2| ofthe:

SCOOPS.

My invention is not particularly concernedwith- I the specific structureof the scoops except insofar as their adaptation for use in connectionwith my improved top stop yokes, one of which is shown at 22, note Figs.1, 2 and 4 of the drawing. The

yoke 22 may also be defined as an elongated rin and comprises upper andlower members 23 and 24 joined by side members 25 and 26.

In originally forming the top stop yoke 22, the

upper and lower members 23 and 24 are bent centrally to a slight extent,thus disposing the sides 25 and 26 angularly to each other, and thisnormal position of the top stop blank is indicated in dotted lines inFig. 3 of the drawing. In this position, the opening between the sidewall members 25 and 26 is sufiicient to provide free passage of the topstop over the ends it and I5 of the scoops.

In Fig. 3 of the drawing I have diagrammatically illustrated a manner ofattaching the top stop 22 to end scoops l2 of astringer, which consistsin moving two tools or jaw members 29 and 30 into engagement with theside members 25,

and 26 of the top stop, and then toward each other to move the members25 and 26 into the recesses l1 and I8 by increasing'the bend, as at 21.The members 25 and 26 entering the recesses I1 and I8 will permanentlyretain the top stop 22 against displacement from'the three scoopsarranged within the now smaller opening 28,

,as will clearly appear from a consideration of acaacoo Figs. 1 and 3 ofthe drawing. The side members 25 and 26 are disposed within the sideboundaries of the scoops, thus permitting the scoops to enter thechannels of the conventional sliders, which are well known in this art.The stops 22 form blocking elements preventing the coupling of scoops ofopposed stringers and this blocking will take place'within'the bounds'ofthe slider,'at least with respect to the innermost scoops arrangedwithin the top stop yoke or element. In Fig. of the drawing is shown aslight modiflcation wherein the top stop 3| comprises what might betermed a multiple yoke. In other words,

ers where it would be desirable to check move- It will be apparent thatthe recessed surfaces oi the coupling end portions of thef'scoops may besaid to form'on these coupling end'portions reduced necks for thereception of the top-stop member or yoke.

the side members 32 and 33 instead of being joined just by top andbottom members 34 and 35 are also Joined by two intervening members 36which form three openings 31 instead of the one large opening 23. Thetop stop 3| is adapted specifically for mounting on three scoops, andthe three scoops will be free to pass through the openings 31, themembers 36 being disposed between adiacent scoops; as will be'apparent.Aside from this change in construction, the top stop 3| will be the sameas that shown in Figs. 1 to 4 inclusive and arranged in positionthe'sameas taught in Fig. 3.

In Fig. 6'of the drawing is shown another top stop '36 which differsfrom the stop 3| primarily in adding to the side members 33 and 40thereoi extending wings or supplemental stop members 4| and 42, thepurpose of which is'to extend beyond the side surfaces of the scoopstoengage the slider, preventing displacement of the slider from the end ofthe'stringer. This type of construction is adaptable for use in what istermed separable stringers. For example; stringers as applied tolumberjackets and similar uses where the two stringers are completelyseparated from each other. In such instances, the slider is retainedalways upon one of the stringers and the top stop of this stringer willinclude the outwardly extending top wings 4| and 42 to retain members43, similar to the members 36 and the three recesses 44 similar-to therecesses 31.

In top stops of the kind defined, these stops can be removed byreversely bending the .stop to the end of spreading the side membersthereof sufliciently to clear the coupling end portions of the scoops.By employing pliable metal in the top stops, a detached or removed topstop can be re-installed into operative position and hand tools, such asa pair of pliers, can be utilized to accomplish this result. Wheresuitable tools are not available, any one of the walls of the top stopcan be cut or ruptured suiliciently to remove the top stop, and then anew top stop can be reapplied. This type of construction-will lenditself to making of repairs by a dealer or distributor or even by thepurchaser. By reason of the simplicity of the device, desired repair canbe quickly and easily accomplished. It will be apparent that allattachments as well as detachments'of the top stops is accomplishedwithout in any way injuring or marring the mounting tape of thefastener, in that the top stop is disposed on the coupling portions onlyof the scoops and beyond the limits of the tape edge. It will also beunder- The yoke considered as an article of manu- I facture may be saidto comprise a body defined by side and end bars, resulting in the yokeshaped contour of the body. Also, the side bars may be joined bysupplemental or intermediate bars which would result in forming a yokehaving several recesses or openings.
